Use the templates or custom code as others have said, no matter what
a Feature will always have an identifier, based on a primary key or
just made up to make the WFS standard happy, there's no way to actually
remove, but as others said you can make up a template that just does
not display the FID.

Alias is really a misnomer, when you set it, it's really the new name of
the layer, not an alternate way to call the layer. that is, it makes
the native name disappear completely and takes its place.

There are two ways to achieve this:
- flip the order so that strees get drawn before house numbers. Labels
   are drawn in the order the layer they come from appear, so lower
   layers always get their label drawn, the others fight with the
   space left free by them
- use the Priority SLD option to change the order in which the labels
   are drawn, see the documentation here:
